INCANDESCENT-LAMP-ATTACHING IMPLMENT.

Specification of Letters Patent.

Patented Mar. 30, 1915.

Application led August 3, 1914. Serial No. 854,859.

To all 'whom 'it may concern Be it known that we, CLAYTON D. Buss and FRANK HnAoooK, citizens of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania, have invented certain new and useful 11nprovernents in Incandescent-Lamp-Attaching lmplements; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to incandescent attaching implements.

The object of the invention resides in the provision of an implement of the character named which may be employed for rotatably inserting an incandescent lamp in its receiving-socket or detaching the same therefrom, and which may be readily operated at various angles and under conditions where the lamp is disposed beyond the reach of the operators hand.

lVith the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts t0 be hereinafter more fully described and particularly pointed out in the appended claim.

1n describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which- Figure 1 is a side elevation of the implement with the parts thereof in the position they would occupy/'when same is operated under normal conditions; Fig. 2, a view similar to Fig. 1 with the parts of the implement positioned to permit the operation of same at an angle Fig.w3, a longitudinal section of the implement, and Fig. 4, a section on the line 4-4 of Fig. 1.

Referring to the drawings the implement is shown as comprising a shaft A including rigid terminal sections 10 and 11 and an intermediate flexible section 12. The sections 1() and 11 are rotatable in bearings 13 and 14 respectively and projecting laterally from the bearing 13 is a threaded stud 15, while a corresponding stud 16 projects laterally from the bearing 14. Pivotally mounted on the stud 16 is a bar 17 provided with openings 18 adapted to be interchangeably engaged over the stud 15 to secure the sections 10 and 11 in angular relation to eect easy rotation of incandescent lamps when same are mounted out of reach of the operator and at an angle to the vertical.

Secured to the section 11 is a plurality of longitudinally disposed resilient strips 21 the outer ends of which are curved outwardly as at 22 so as to conform substantially to the shape of an incandescent lamp.

The outer ends of the strips 21 are each covered with a soft resilient material 23 such as rubber. These strips 21 constitute gripping lingers and are normally held in contracted relation by means of a spiral spring 24 having its inner end fixed to the section 11 and its outer end free to slide upon the strip 21. This spring is under slight tension and as a result will always clamp the outer end of the strips upon the lamp with sufficient firmness to effect rotationof the latter when the shaft A is rotated.

1f it is desired to release the strips 21 a hook 19 is employed, the latter being engaged over the outermost coil of the spring 24 and having secured thereto a connection 20 whereby the hook may be pulled and the spring 24 compressed to release the fingers 21 as will be obvious.

What is claimed is An implement of the character described comprising a shaft including rigid terminal sections and a flexible intermediate section, bearings in which the terminal sections rotate respectively, a rigid bar having one end pivoted to one of said bearings and d tachably engaged with the other bearing for locking the terminal sections of the shaft in angular relation to each other, ble strips secured to one of the terminal sections longitudinally of the latter and forming gripping fingers for embracing a 1ne1n- In testimony er to be rotated, a spring encircling said tures, 1n the pr fingers with its inner end anchored to the whereof, We afx our signaesence of two Wltnesses.
